Intraosseous hemangiomas.

Intraosseous hemangiomas are classified as benign tumors of vascular nature. Some authors describe them as hamartomas. They originate and expand inside bone structures. They are usually congenital, rarely of posttraumatic origin. In the Maxillo-Facial Surgery departments of the Universities of Rome "La Sapienza" and "Tor Vergata," from 1990 to 2004, 11 cases of intraosseous hemangioma have been diagnosed. In 6 cases, the neoplasm localized in the zygomatic region; in 3 cases, at the mandible level; in 1 patient, in the maxillary site; and in 1 patient, in the frontal bone. Literature review and the case of a male patient affected by left orbitozygomatic hemangioma are described.
